1Two-stage vs single-stage management for concomitant gallstones and common bile duct stones显示文摘AIM:To evaluate the safety and effectiveness of twostage vs single-stage management for concomitant gallstones and common bile duct stones.METHODS:Four databases,including PubMed,Embase,the Cochrane Central Register of Controlled Trials and the Science Citation Index up to September 2011,were searched to identify all randomized controlled trials(RCTs).Data were extracted from the studies by two independent reviewers.The primary outcomes were stone clearance from the common bile duct,postoperative morbidity and mortality.The secondary outcomes were conversion to other procedures,number of procedures per patient,length of hospital stay,total operative time,hospitalization charges,patient acceptance and quality of life scores.RESULTS:Seven eligible RCTs [five trials(n = 621) comparing preoperative endoscopic retrograde cholangiopancreatography(ERCP)/endoscopic sphincterotomy(EST) + laparoscopic cholecystectomy(LC) with LC + laparoscopic common bile duct exploration(LCBDE);two trials(n = 166) comparing postoperative ERCP/EST + LC with LC + LCBDE],composed of 787 patients in total,were included in the final analysis.The metaanalysis detected no statistically significant difference between the two groups in stone clearance from the common bile duct [risk ratios(RR) =-0.10,95% confidence intervals(CI):-0.24 to 0.04,P = 0.17],postoperative morbidity(RR = 0.79,95% CI:0.58 to 1.10,P = 0.16),mortality(RR = 2.19,95% CI:0.33 to 14.67,P = 0.42),conversion to other procedures(RR = 1.21,95% CI:0.54 to 2.70,P = 0.39),length of hospital stay(MD = 0.99,95% CI:-1.59 to 3.57,P = 0.45),total operative time(MD = 12.14,95% CI:-1.83 to 26.10,P = 0.09).Two-stage(LC + ERCP/EST) management clearly required more procedures per patient than single-stage(LC + LCBDE) management.CONCLUSION:Single-stage management is equivalent to two-stage management but requires fewer procedures.However,patient's condition,operator's expertise and local resources should be taken into account in making treatment decisions.Jiong Lu Yao Cheng Xian-Ze Xiong Yi-Xin Lin Si-Jia Wu Nan-Sheng Cheng 2012World Journal of Gastroenterology2012,18,24:107
2Outline of the Report on Cardiovascular Disease in China,2010显示文摘Major and profound changes have taken place in China over the past 30 years.Rapid socioeconomic progress has exerted a great impact on lifestyle,ranging from food,clothing,working and living conditions,and means of transportation to leisure activities and entertainment.At the same time,new health problems have emerged,and health services are facing new challenges.Presently,cardiovascular diseases (CVD) are among the top health problems of the Chinese people,and pose a serious challenge to all engaged in the prevention and control of these diseases.An epidemic of CVD in China is emerging as a result of lifestyle changes,urbanization and longevity.Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures.Since 2005,guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China,nationwide experts in the fields of epidemiology,clinical medicine and health economics in the realms of CVD,cerebrovascular disease,diabetes and chronic kidney disease,completed the Report on Cardiovascular Diseases in China every year.The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD.In addition,as the report is authoritative,representative and readable,it will become an information platform in the CVD field and an important reference book for government,academic institutes,medical organizations and clinical physicians.This publication is expected to play a positive role in the prevention and control of CVD in China.We present an abstract from the Report on Cardiovascular Diseases in China (2010),including trends in CVD,morbidity and mortality of major CVDs,up-to-date assessment of risk factors,as well as health resources for CVD,and a profile of medical expenditure,with the aim of providing evidence for decision-making in CVD prevention and control programs in China,and of delivering the most authoritative information on CVD prevention and control for all citizens.HUSheng Shou KONG Ling Zhi GAO Run Lin ZHU Man Lu WANG Wen WANG Yong Jun WU Zhao Su CHEN Wei Wei LIU Ming Bo For the editorial board 2012Biomedical and Environmental Sciences2012,25,3:93

4Western North Pacific Tropical Cyclone Database Created by the China Meteorological Administration显示文摘This paper describes the access to, and the content, characteristics, and potential applications of the tropical cyclone(TC) database that is maintained and actively developed by the China Meteorological Administration, with the aim of facilitating its use in scientific research and operational services. This database records data relating to all TCs that have passed through the western North Pacific(WNP) and South China Sea(SCS) since 1949. TC data collection has expanded over recent decades via continuous TC monitoring using remote sensing and specialized field detection techniques,allowing collation of a multi-source TC database for the WNP and SCS that covers a long period, with wide coverage and many observational elements. This database now comprises a wide variety of information related to TCs, such as historical or real-time locations(i.e., best track and landfall), intensity, dynamic and thermal structures, wind strengths, precipitation amounts, and frequency. This database will support ongoing research into the processes and patterns associated with TC climatic activity and TC forecasting.Xiaoqin LU Hui YU Ming YING Bingke ZHAO Shuai ZHANG Limin LIN Lina BAI Rijin WAN 2021Advances in Atmospheric Sciences2021,38,4:96
5Peat record reflecting Holo-cene climatic change in the Zoige Plateau and AMS radiocarbon dating显示文摘Through the use of reliable AMS dating of high resolution (15-30 years) peat and the establishment of monsoon climate proxies sequence, we have been able to recognize several cold, dry events in the Tibetan Plateau during the Holocene. The more obvious ones occurred around 12800, 11300, 10200, 9580, 8900, 6400, 4400, 3700, 2800 and 1500 cal. aBP. These events correlate well with both ice rafting events recorded in high latitude North Atlantic Ocean sediment cores and cooling events in the low latitude SST. Spectral analysis indicates high frequency climate variation on centennial-millennial time scale during the Holocene. This further reflects Holocene climate instability and the existence of centennial-millenium scale rhythm in mid latitude areas as well.ZHOU Weijian LU Xuefeng WU Zhengkun DENG Lin A.J.T.Jull D.Donahue W.Beck 2002Chinese Science Bulletin2002,47,1:68

10Persistence and clearance of viral RNA in 2019 novel coronavirus disease rehabilitation patients显示文摘Background:A patient’s infectivity is determined by the presence of the virus in different body fluids,secretions,and excreta.The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease(COVID-19)remain unclear.This study analyzed the clearance time and factors influencing 2019 novel coronavirus(2019-nCoV)RNA in different samples from patients with COVID-19,providing further evidence to improve the management of patients during convalescence.Methods:The clinical data and laboratory test results of convalescent patients with COVID-19 who were admitted to from January 20,2020 to February 10,2020 were collected retrospectively.The reverse transcription polymerase chain reaction(RT-PCR)results for patients’oropharyngeal swab,stool,urine,and serum samples were collected and analyzed.Convalescent patients refer to recovered non-febrile patients without respiratory symptoms who had two successive(minimum 24 h sampling interval)negative RT-PCR results for viral RNA from oropharyngeal swabs.The effects of cluster of differentiation 4(CD4)+T lymphocytes,inflammatory indicators,and glucocorticoid treatment on viral nucleic acid clearance were analyzed.Results:In the 292 confirmed cases,66 patients recovered after treatment and were included in our study.In total,28(42.4%)women and 38 men(57.6%)with a median age of 44.0(34.0-62.0)years were analyzed.After in-hospital treatment,patients’inflammatory indicators decreased with improved clinical condition.The median time from the onset of symptoms to first negative RT-PCR results for oropharyngeal swabs in convalescent patients was 9.5(6.0-11.0)days.By February 10,2020,11 convalescent patients(16.7%)still tested positive for viral RNA from stool specimens and the other 55 patients’stool specimens were negative for 2019-nCoV following a median duration of 11.0(9.0-16.0)days after symptom onset.Among these 55 patients,43 had a longer duration until stool specimens were negative for viral RNA than for throat swabs,with a median delay of 2.0(1.0-4.0)days.Results for only four(6.9%)urine samples were positive for viral nucleic acid out of 58 cases;viral RNA was still present in three patients’urine specimens after throat swabs were negative.Using a multiple linear regression model(F=2.669,P=0.044,and adjusted R2=0.122),the analysis showed that the CD4+T lymphocyte count may help predict the duration of viral RNA detection in patients’stools(t=-2.699,P=0.010).The duration of viral RNA detection from oropharyngeal swabs and fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group(15 days vs.8.0 days,respectively;t=2.550,P=0.013)and the duration of viral RNA detection in fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group(20 days vs.11 days,respectively;t=4.631,P<0.001).There was no statistically significant difference in inflammatory indicators between patients with positive fecal viral RNA test results and those with negative results(P>0.05).Conclusions:In brief,as the clearance of viral RNA in patients’stools was delayed compared to that in oropharyngeal swabs,it is important to identify viral RNA in feces during convalescence.Because of the delayed clearance of viral RNA in the glucocorticoid treatment group,glucocorticoids are not recommended in the treatment of COVID-19,especially for mild disease.The duration of RNA detection may relate to host cell immunity.Yun Ling Shui-Bao Xu Yi-Xiao Lin Di Tian Zhao-Qin Zhu Fa-Hui Dai Fan Wu Zhi-Gang Song Wei Huang Jun Chen Bi-Jie Hu Sheng Wang En-Qiang Mao Lei Zhu Wen-Hong Zhang Hong-Zhou Lu 2020Chinese Medical Journal2020,,9:58

12Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing.Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group 2020National Science Review2020,7,12:51

17Immunohistochemical study on p53,H-rasp21,c-erbB-2 protein and PCNA expression in HCC tissues of Hart and minority ethnic patients显示文摘AIM To find out the difference of humanprimary liver carcinogenesis between Han andminority ethnic patients in Xinjiang.METHODS Expression of p53,c-erbB-2,H-rasp21 protein and proliferating cell nuclearantigen(PCNA)in tumor tissues of 50 patients(Han 38,minority 12)with primary hepaticcarcinoma was detected byimmunohistochemistry(LSAB).RESULTS The positive frequency of p53,c-erbB-2,H-rasp21 and PCNA expression was46.0%(23/50),70.0%(35/50),68.0%(34/50)and 82.0%(41/50)in tumor tissues;4.0%(2/50),22.0%(11/50),64.0%(32/50)and 52.0%(26/ 50)in peritumors respectively and asignificant difference,except for H-rasp21,ofoncogene alteration was found(P<0.05)between tumor and non-tumorous tissues.Combined the three oncogenes alteration,26%(13/50)tumor tissues had positiveimmunoreactivity,but in peritumor and normallivers it was negative.The positive rate of p53,c-erbB-2 and H-rasp21 protein expression was39.5%(15/38),60.5%(23/38)and 39.5%(15/38)in tumors of Han patients;66.7%(8/12),100%(12/12)and 75.0%(9/12)in minoritiesrespectively,with statistical difference (P<0.05).CONCLUSION Overexpression of p53,c-erbB-2and H-rasp21 in human primary liver carcinoma isan important biomarker of genetic alteration.The different frequency of these oncogeneticchanges may reflect some environmental or/andethnic hereditary factors affecting the livercarcinogenesis.The special life style of Han,Uygur,Kazak and Mongolia nationalities inXinjiang may also be related to theetiopathogenesis of this disease.Guo Yue Lin Zhao Lun Chen Cai Mo Lu Ying Li Xiao Jia Ping Rong Huang Department of Laboratory Medicine,Chinese PLA 474 Hospital,Urumqi 830011,Xinjiang Uygur Autonomic Region,China Department of Pathology,the 1st Teaching Hospital,Xinjiang Medical University,Urumqi 830054,Xinjiang Uygur Autonomic Region,China 2000World Journal of Gastroenterology2000,6,2:40
18Chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum显示文摘The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How Chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the Chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern China had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern China had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern China had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern China were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of Chinese deserts and sand fields are controlled by regional climate together with human activity.LU HuaYu YI ShuangWen XU ZhiWei ZHOU YaLi ZENG Lin ZHU FangYing FENG Han DONG LiNa ZHUO HaiXin YU KaiFeng MASON Joseph WANG XiaoYong CHEN YingYong LU Qi WU Bo DONG ZhiBao QU JianJun WANG XunMing GUO ZhengTang 2013Chinese Science Bulletin2013,58,23:40
